I checked all logs up until the log where you said
2016-02-08_09-06-21-
"[09:06:41] [BOSS]TheKillerKid: where r my money =-=""
[09:07:08] You currently have:[ $0 ] in your bank account.
[09:07:08] [BOSS]TheKillerKid: !bank
[09:07:10] [BOSS]TheKillerKid: usman?
None of the logs before this show you giving any money, and there is no log for when you first registered the nickname [BOSS]TheKillerKid. Like I said, there is no log for the 7th which is when you first registered the nickname and last used the Bear account. Where are these logs?
On a final note, sorry, we can't help you. As I said, every time you join there is a message in the chatbox telling you to use the website to transfer account stats. Every so often on the server appears a similar message in the chat box.
You've been playing on various accounts for a large number of hours on Littlewhiteys:
TheKillerKid (PAC: 25598): littlewhitey's 0.4: 46.4 hrs
[BOSS]NoFearForBear: littlewhitey's 0.4: 84.8 hrs
That is over 100 hours of playtime and you didn't see any of those messages or hear other players about changing their username by PAC at least once?
On a final note, please use the proper method to change names in future to avoid losses/errors of cash when passing large amounts of cash manually between accounts.
